I need your help on this part. I am using a G2 camera now with teleconvertor 2x and wide angle 0.42X (dunno what brand)
What I realise is when using the lenses (the wide angle esp.), there seems to be a dark ring around the image (fish eye view).
I am wondering whether this is because it is lousy lenses or this is a normal phenomenon for digital camera using lenses.
Is there anyway to rectify this? Or can recommend me a better lenses?
Thnx in advance for your help!

Thnx for your reply
But sometimes at full zoom there are still a bit of dark patches at the corners. And what dya mean by using at full wide angle?
Sorry a newbie here.
Thnx for your help!

There will still be vignetting if the convertors are not properly matched to the camera.
If there is a mismatch, vignetting will always be most severe at the wide angle end.
The convertors you bought are probably not that suitable for your camera.

Hmm... that the lenses not suitable?
Juz wodering if that is the case that means it is pretty impossible to combine 2 or 3 lenses to shoot as the vignetting will be more severe (for instance adding polarizer + TC or anything else)?
Any good lenses to recommend and the estimated street price hopefully.
Thnx lots bros!

Have you tried the origianl G2 converters?
for teleconverters, there will be some vignetting, at the camera's full wide-angle, you will need to zoom out a bit to avoid the vignetting.
as for wide-angle converters, there should not be any vignetting, at the camera's wide-angle i.e. you should not be zooming out to avoid the vignetting.
As for stacking, most you should do, is to have a UV filter on the lens adapter, and not use any polarisers with that. The more leayers you got on, the more degradation of quality, and you will lose a couple of stops of exposures.
but before you buy, be sure to check out the prices at AP, CP and MS Color.
